GLT series straight cylindrical ball spline

Ball spline uses balls installed in the outer cylinder of the spline shaft to perform smooth liquid rolling and torque transmission in a precisely ground rolling groove. It adopts a unique contact point design with a larger contact angle (40 °). In addition to its high sensitivity, it can also significantly enhance the load capacity. Suitable for environments with high vibration impact load, high positioning accuracy requirements, and high-speed motion performance, it can also play an effective role in such environments. At the same time, even when used instead of linear ball bushings, the rated load of ball splines is more than ten times that of linear bushings due to the same shaft diameter. So it can make the design very compact, even under the action of cantilever load, torque, etc., it can be safely used and has high durability.

High load capacity

The rolling groove of the ball is precision ground and formed, and adopts Gothic 40 ° angle contact. Due to the large contact angle, it has a large load capacity in both radial and torque directions.

Zero clearance in rotation direction

By using 2-4 rows of relative ball bearings with a contact angle of 40 °, the spline shaft is combined with the spline outer cylinder, and the clearance in the rotation direction can be zero by adjusting the preload method.

Highly sensitive

Due to the special design of the steel ball contact point, it not only has high rigidity but also greater sensitivity and can reduce energy waste.

High rigidity

Due to the large contact angle, it has high rigidity and can be subjected to appropriate preloading depending on the situation, thus achieving high torque rigidity.

Easy assembly

Due to the special design, even if the spline outer cylinder is detached from the spline shaft, the steel ball will not fall off. Therefore, assembly, maintenance, and inspection are all easy to carry out.
